Abstract

PCT No. PCT/IT96/00093 Sec. 371 Date Feb. 13, 1998 Sec. 102(e) Date Feb. 13, 1998 PCT Filed May 7, 1996 PCT Pub. No. WO96/35724 PCT Pub. Date Nov. 14, 1996The object of the invention is to provide a liquid anti-scaler for coating polymerizing reactors obtained by a condensation reaction of naphthol with an aldehydic cross-linking product, wherein the cross-linking product is the reaction product of hydrosulfite and formaldehyde. It contains hydrosulfite and/or radical bisulfites and/or bisulfite. The condensate is made in such a way that in the absence of oxygen, it is in the form of liquid of clear transparent color.
